GAUGING MECHANISM FOR SHOE MACHINES Filed May 19, 1942 4 Sheets-Sheet 4 VE/V TUE Patented Sept. 21, 1943 v N'l T ED STAT s PATIENT tim caoomcivmcnnmsni FOR snon This invention relates to mechanisms by which shoes may be positioned for operations in ma.- chines employed for the attachment. of heelparts, as bases and top-lifts. v f j Inheel attaching.machines, a. shoe, presented to fastening-inserting mechanism uponafljack or like support, is capable of some angular'move ment about the longitudinal axis. of the jack. An examplejof a machine in which this may occuris found in Letters Patentof the United States No. 1,157,688, GliddenjO ctober 26,1915. To locate theheel-seat of the shoe in the desired relation toa heel or top-lift presented ina ring,

swing-plate or other holder, the operator varies the angle of the shoe until he believes that the breast-line of the heel .or top-lift lies at a proper angle across the shank of the shoe, and the peripheries of the heel-seat and those of the heelparts correctly register. fected by mere inspection of the work, a method which does not give satisfactory re'sults'unless the operator is quite skillful, or an undue amount of time is spent. An object of this invention is to enable an operator to determine rapidly and accurately theangularj position of a shoe with relation" to a part to be attached to it, this being accomplished by means which in no way interferes with the manipulation of" the Work or of partsof the machine.

In the attainment of the. above object, there is combined'with fastening-inserting mechanism and a co-operating jack or like work-support, gauging means into contact with which a shoe, preferably at the forepa'rt, maybe brought, and a mounting for the gauging" means situated in front of the inserting mechanism and normally spaced vertically from the work, as below the shoe-support in an inactive position. Here, it is clear of all parts which theoperator must manipulate or have ready access to, as thejack or the holder for the heel 'portions, and is alsoremoved from the exposed parts of the inserting mechanism. Yet, by mounting the gauge for movement into the plane of the work, there is furnished meansby which said work may be located positively by touch, and without the necessity for inspection. Upon its mounting, the gauging means, which may consist of spaced members for the; reception of contact by right and left shoes, 1

maybe varied in position .for the purpose of correctly presenting shoes of different widths to the heel-holder and the inserting mechanism for the inserting operation, and'this position is preferabl indicated visually tothe operator by.

means actuated by the gauging means. The

This is commonly efmovement of the gauging meansbetwee'n inactive and'active positions is most advantageously effected by 'transmitting to itthe movement of the work-support, shiftedintoand out of operating relation at the inserting mechanism. In such heel-attaching machinesas' that of the previously mentioned patent, afprotectiveguard is provided for the inserting mechanism, and this furnishesja most effective meansup'on, which to mount movably the, gau ing means, This guard being pivoted for movement with respect to the inserting mechanism, interference with the transmission 'of' the movement of the work-.fsupport'to thegahgin'g means"ma'y be prevented by' making .one of "the transmitting elements "move about. the pivot of the guard; i With the gauging vmeans may be associated means, as an element through which said gauging, meansis adjusted, furnishing a bottom-rest'for the shoe being operated upon, so as saiid"shoe is 'beingcarried'into operating position it will, without efiort on the part of the operator, be located vertically 'forjpresentation to'either of spaced right and left members, and. there maintained during the gauging movement. Byjmaking this rest y'ieldable, it will'be caused to accommodate itself. to {the level at which the tread surface o f the' outsole of. the shoe moves into operating position, andalso to changes in between these elements may include yieldable means to compensate for differences in the extent of the two movements. As herein disclosed,

eachof a pair of right and left gauges is mounted upon a verticallyv movable rack,- and both (the jack andigauges are geared tosan intermediate verticalshait. Preferably included in the.con-',

nections is a slide-rod, acting upon a lever geared tothe gaugeracks and actuatedth'rough a rack which'ismovable upon it. Thelast-mentioned rackris shownas operated. by a pinionfupon the vertical shaft, it acting at one end upon a' collar,v

variable iniposition. upon the rod, and at the opposite endupon a springinterposedbetween the rack [and rod. The slide-rod, as it is shifted .under the influence of the jack, acts positively upon the gauge-lever .during movement in one direction, and yieldablythrough a compensating connection upon movement in the opposite direction. This compensating connection also allows movementof the guard about its-pivotwithout interference by' the gauge-actuating connecwhich .takes place [as it is included in a heel-attaching machine, of which a portion is shown in side elevation;

Fig. 2 is a front elevation thereof;

Fig. 3, an enlarged top plan View of the gang-,- ing mechanism;

Fig. 4, a side elevation taken from the right in Fig. 3; and

Fig. 5, a horizontal sectional detail, .on the line VV of Fig. 4.

Of the several machines to which the present gauging mechanism may usefullybe applied, one is that disclosed in the patent to which reference has already been made. of this, there is shown herein the frame IlLhaving movable ver-' tically in an overhanging portion a plunger 12, upon the head of which is guided horizontally a slide l4. At 1.6 is pivoted tothe slide a worksupporting jack l8, provided at its lower end with a last-pin .20 adapted to receive the pinhole of ,a last L within a shoe .8 to which a heel is to be attached. The jack may be moved about its pivot from the work-receiving position of Fig. 1 to the operating position of Fig. 4. The jack presents the WQrk to nail-inserting mechanism including a die 22 .carried upon a crosshead 2.4, and in the nail-holding passages of which reciprocate drivers 26 rising from a second crosshead 28, both crossheads being guided for vertical reciprocation in the frame. A heel-base and ,a lift, which .are to .be attached to the heel-seat of the shoe, are presented above the die in superposed relation by a holder H, which may be that of Letters Patent .01 the United States No. 1,723,310, Standish, August .6, 1929. Downward movement of the jack by the plunger 12 applies preliminary pressureto the work, after said jack has been swung into operating position above the nailing die, while .elevationnof the crosshead ,24 gives final clamping pressure. Then, the drivers25 rise to insert the nails which they bear ,upon their ends. "Across,

the front and ,at thesidesof the inserting mechanism M lies a protective guard .30, pivoted at 32 upon the frame. The uard ishollow or recessed, having a vertical front .wall from which side andtop walls extend rearwardly, while the rear and lower portions are .open. It appears in the drawingsin active position in full lines, and in Fig. 1 is shown in dash-lines as lowered to give access to the nailing mechanism.

Considering nowthe gauging mechanism'of this invention, attached to the front wall of the guard 30 at opposite sides are guides 40,, 40, in, which are movable vertieaily rack-bars 42, 42,, having fixed to their upper ends laterallyfiex-,

tended right and left heads .44 and 46, respectively. Resting'upon the plane horizontal sur face of each head is a carrier-blockdil, to which is pivoted at 50 an elongated gauge member, the member 52 being at the right upon the head 44 and the member 54 at the left upon the head 46. A leaf-spring 55,-attached to each block and bearingupon a projection from the side of Fig. 1 shows my improved gauging mechanism the gauge, holds the latter down into a substantially horizontal position when lifted to its active relation, as in Fig. 4, but allowing it to yield upon engagement wtih the guard when lowered and inactive, as in Fig. 1. In the latter position, a portion of actuating mechanism for the gauges rests in depressions 58 (Fig. 4) at the front of the guard. This arrangement increases the possible extent of retraction and more completely removes the gauges from the front of the holder H. If a right jacked shoe is turned about the last-pin 20, when the jack i8 is in the inward position of Fig. 4, the bringing of the inner side of the outscle at the point of maximum projection at the ball-line against the inner side of the raised gauge 52 will correctly position the shoe about the vertical axis of the jack for the attachment of its heel and lift in the holder H. The opposite gauge 54 serves similarly to locate the left shoe. Contact of the indicated portion of the shoe-soles with the gauges so removes the gauging point from the heel-seat, that, as the apex of the angle subtended is approached, the angular displacement of the heel-seat is minimized. Conse quently, one transverse position of the gauges will serve for a considerable number of widths, and any possible error in the relation of the heel-seat introduced by inaccurate gauging is lessened. The length of the gauge members is such that they will be engaged properly by all sizes of shoes.

Means is provided for locating the gauges 52, 54 for co-operation with shoes of all widths. For this purpose, there is threaded into the carriers 48 right and left screws 60 and 6!, respectively, formed upon a rod 52 rotatable in an enlargement 64 on the head 44. Into an enlargement E6 upon the opDOsiterack-head, a tubular screw 68 is threaded and having a head or finger-piece T0.

Through this screw 68 passes a reduced portion E2 of the rod. A shoulder 14 upon the rod abut-s against the inner end of the tubular screw, while a collar '76 fast .upon the rod-portion 12 contacts 7 with the outer side of the head 79. When the rod '62 is turned by a finger-piece I8, the rotation forming the operator as to the of the right and left screws carries the gauges to-, ward or from each other to locate the bars 52, 54 for gauging shoes of various widths. By rotating the screw 68, both gauges may be shifted simultaneously longitudinally of the axis of the rod 62, either to the right or to the left, this being particularly designed to give a setting-up adjustment. This screw 63 may be locked against displacement by dividing the enlargement 66 and clamping it by a screw To facilitate the setting of the gauges 52 and 54, there is rotatable in the enlargement 64 a short horizontal shaft 32, extending forwardly through an opening in a, dial-plate 83 attached to the front of the enlargement. Outside the plate, the shaft carries a hand 84- movable over a series of index-marks 85 inscribed upon the face of the dial, these marks corresponding to shoe-widths. At the inner side of the dial a pinion 87 is fast upon the shaft, and has meshing with it a rack 88 projecting from the carrier of the gauge 52. As the gauges are adjusted by rotation of the finger-piece 1B, the gearing moves the hand over the dial, the reading which it furnishes at the index-marks incorrect location of thegauges.

The movement of the gauges between their lowered inactive and raised active positions is accomplished by a connection to the Jack 18. Piv- Joted at 90 to said iack (l=ig..l) is a link, which is formed in inner and 'outer'sections92 and 94, re-

spectively, they being fixedly connected to each "other by screws 96. the length of the link to compensate for adjust- E This permits a variation in ment of the jack by the operator fore and aft of the machine in its waysby movement of the slide I141. The link-section 94' is joined'at 98 to a rack I03, guided horizontallyin an extension I02 from .the head of the. plunger I2. With the rack- 'm'eshe's'a pinion .I 34 fast upon the end of a short vertical 'shaft'llifi, journaled in a horizontal bracket I03 fixed to the frame. Belowthe pinion I04, apinion III] is secured to the shaft (Fig; 3) and'isin mesh with teeth uponthe inner end of a. rack-bar II2, movable horizontally in the bracket I38; .The rack-bar has at its-opposite "extremity a series;of teeth engaginga pinion I I4 through a bore in the rack is a horizontal rod I23, i

which is compelled to move positively with said rack in onedir'ection by a collar I28 adjustable along the rod. It is yieldable in the opposite direction by compression of "a spring I39, interposed between the rack and a nut and lock-nut at I32 upon the rear extremity of the rod. At the forward end of the rod is an enlargement I33, rectangular in cross-section and guided to slide in the frame. In this enlargementis ahor'izontal bore containing'a compression-spring I34, this contacting at its forward end with a telescoping, compensating rod-section: I36. This rod I36is joinedby a link I38 to'the short arm I40 of a lever I42, fulcrumed about the pivot-pin 32 upon which turns the guard 30 of the nailing mech-v anism M. .1 The upper extremity'of the lever I42 has formed upon it a gear-segment I 44, this being in mesh with a pinion I43 uponahorizontal shaft I48 journaledtransversely near. the. top of the guard. Upon this shaft are secured two pinions I50; I53,.which engage, respectively, the, racks 42 of the gauges 52 and 54. Theextent of movement of the racks and gauges is limited downwardlyby the seating of the rod. 52 in the depressions 58 at the front of the guard-30, and; adjustablylin the opposite direction by the engagement of the collar I28 with the endvofthe guide I24. A contact-screw I54 is threaded through a shoulder at the forward extremityof the rod-enlargement I33 and by contact with thelever-arm I40, turns the segment I44 contraclockwisek l V The relationiof the elements inthe'co-nnecting chain just described, between the jack I8 and the gauges 52, 54, issuch, that when the jack is in its forward work-receiving. position the gauges are lowered close to the top of the guard 30, then yielding against their springs 56, as appears in Fig. 1. When the jack is swung in to operating position (Fig. 4), it rotates, through the link 92, 94 and intermediate gearing, the shafts I06. and H6 to carry the rack I22 tothe right in Fig. 1. This, through the spring I35, the slide-rod I26, I33 and the contact-screw I54, turns the lever I42 contraclockwise, and, by the rotation of. the shaft I48 geared to it. elevates the racks 42 with the gauges 52 and 54. The level to which these gauges rise may be determined by the setting of the contact-collar I28 on the rod-portionI'26. They are now in a horizontal planewinlwhich the outsole of the shoe S upon the jack III. will move into nailing position, and along this plane "the work is'guided by the engagement of the threadsurface of the outsole'with the central portion of the gauge-adjustingredBZ. Upon this rod as a bottom-rest, the operator may swing the forepart of 'the s'hoeabout the longitudinal axis of th e' jack. If it is a right shoe, the inner side of 'the' outsole-at the portion of maximum projection at the breast-line will contact with the inner vertical surface of the right-handgauge 52. This positions the-heel-seat of the shoe correctly, as

to its angular relation in a horizontal plane, with respect to a heel and lift in the holder H. The opposite g 'uge54 serves similarly to locate the left shoe. If theracks 42 tend to be lowered by a force created by engagement of the work with the rod 62; the-movement is transmitted through the gearingI4BgI44, lever I42 and contact-screw I54 to the rod I23, I33. The resulting compression of the spring I33 allows the gauge mechanism to yield downwardly, and to yield'farther when the clamping pressure goes on the work. It also compensates for differences in the extent of inward movement of the jack and upward movement of the gauge mechanism. The heelingoperationhaving been completed and the jack I8 carried out'to work-receiving position by the operator, the connections previously outlined move the rod I23, I33 to the left in Fig. 4. This lowers the racks '42 through the rod-section I33 and link I38, the spring I34 compressing and absorbing any excess of movement of the jack over that of the gauges. 1 I [f'theoperator desires access to the nailing mechanism M, he swings outwardly and downwardly the guard 33. At this time, the contraclockwise movementof the arm I40'of leverv I42 (Fig; 4) ca'usesthe' connection between'the leverarm and the link I38to break upwardly. This is permitted' by the compression of the spring 'I 34 by the rod-section 'l33'fwhile th'e rod I26, I33 remains" at rest. A contact member I53 upon the frame receives engagement of the link as it is carried up, and thus limits'the extent of movement offthe lever I42 Since the fulcrum of this lever and-the pivot of the guard coincide, there is no interference with the movement of said uard.
